[ci] Enabled slurmdbd in docker compose

[teojgo]

Closes #3382

Looks good to me except that I think that there should be a dependency to prevent fronted to start before any other Slurm containers. If you pull and create from scratch all the Docker compose containers and try to run with the slurm backend one of the tutorial examples, you will get:

sbatch: error: Batch job submission failed: Unable to contact slurm controller (connect failure)

If you shutdown and rerun docker compose, frontend will be brought up at the end and the test will run fine.

Yes, I need to look at it a little more to ensure that the slurm cluster is up before going on and add a health check for this
